The problem of selecting pair-potentials of finite range for Gibbs random fields is considered as an important step in modelling multi-textured images. In a decision theoretic set-up, the Bayesian procedure is approximated by using Laplace's method for asymptotic expansion of integrals. Certain frequentist properties of the selection procedure are investigated. In particular, its consistency is...

Morpheme analysis is very important for Uyghur language processing. Morpheme analysis of Uyghur is quite different from other language, for this task the keys include feature selection and the design of a morpheme annotated corpus . In this paper we propose a new statistical-based Uyghur morpheme analysis method by using Conditional Random Fields (CRFs) model. The preliminary experiment results...

We construct various boundary states in the coset conformal field theory G/H. The G/H theory admits the twisted boundary condition if the G theory has an outer automorphism of the horizontal subalgebra that induces an automor-phism of the H theory. By introducing the notion of the brane identification and the brane selection rule, we show that the twisted boundary states of the G/H theory can b...
